Kill in script not killing all processes (HPUX)

Hi

I have a script running overnight to kill jboss process ..

Code:

for i in `ps -elfx|grep -i JBoss|grep -v grep|sed 's/[ ][ ]*/,/g'|cut -d',' -f4`

do

echo killing process $i

kill -9 $i

done

however, the script isn't killing off all the processes.

If I run the ps command, it is picking up all the processes correctly.

This seems to randomly happen.

I have tried running the script as the user of the procesess and as root, with the same random results.

Any idea's?

PS: This is on HPUX.

Thanks in advance

yes, some processes cannot be killed (at all). It depends on the state of that process (or better to say what's happening currently in that process).
